Fossil is a simple, high-reliability, distributed software configuration management system (…)

This entire website is just a running instance of Fossil. The pages you see here are all wiki or embedded documentation or (in the case of the download page) unversioned files. When you clone Fossil from one of its self-hosting repositories, you get more than just source code - you get this entire website.
